VEHICLE-BRAKE.

SPECIFICATION forming part of Letters Patent No. 688,328, dated December 10, 1901.

Application tiled December 18, 1899. Renewed May 2l. 1901. Serial No. 61.316. (No model.)

T0 all whom, it may concern:

Be it known that we, ROGER J. ONG and AN- DERSON J. DOUGLAS, citizens of the United States, residing at Yates Landing, in the county of Pulaski and State of Illinois, have invented certain new and useful Improvements in Vehicle-Brakes, of which the following is a specification..

Our invention relates to vehicle-brakes; and its object is to provide improved means for throwing the brake-shoes into frictional engagement with the wheels of the vehicle and for releasing the brake-shoes and throwing them away from the wheels to prevent the accumulation of mud on either the brakeshoes or wheels.

The construction of the brake will be fully described hereinafter and defined in the appended claims, in connection with the accompanying drawings, which form a part of this specification.

In the drawings, Figure 1 is a view in perspective of the under side of a Wagon-bed with our im proved brake in position thereon. Fig. 2 is a transverse vertical section, and Fig. 3 is a transverse vertical section through one of the supporting-brackets of the brakeshoe arms.

The reference-numeral l designates the bed of the wagon, from opposite sides of which project brackets2 and 3. The upper brackets 2 extend through the sides of the bed, and the lower brackets are secured to the under surface of the bottom of the wagon by bolts 4, which extend through angle-plates 5,which latter are secured to the inner surfaces of the sides of the Wagon-bed by bolts 6 and have openings for the passage of the upper brackets 2.

The brake-shoe arms,arranged one at either side of the wagon, comprise vertical posts or spindles 7, supported pivotally in bearings formed in the brackets 2 and 3, and outwardly' and downwardly turned arms S, carrying shoes 9 at their outer ends.

lOdesignates a crank-'shaft supported below the wagon-bed in front of the brake-shoe arms by bearings 11. One end of this shaft 10 is bent downward at right angles to form a crank 12, which is connected by a link or rod 13 to the adjacent brake-shoe arm. To the opposite end of the shaft 1O is centrally secured a bar 14, constituting a double crank, one end of which is connected by a link or rod 15 with the adjacent brake-shoe arm, while the opposite end of said double crank 14 is connected by a rod 16 to a lever 17, fulcrumed to one side of the Wagon and carrying a dog 18, adapted to engage a notched segment 19, secured to the wagon.

The operation of the mechanism above described will be readily understood. By pulling upon the lever 17 the shaft 10 is oscillated and the arms 8 are swung forward on their pivotal supports into engagement with the wheels. A reverse movement of the lever moves the brake-shoe arms and shoes clear of the wheels, allowing mud to drop away from the wheels and preventing accumulation of mud and dirt on the shoes or wheels.

We claim- 1. The combination of a wagon-body, of brackets secured at its opposite sides, brakeshoe arms pivotallyT mounted therein; brakeshoes carried by said arms, a crank-shaft arranged transversely of the Wagon-bed supported in brackets in front of said arms; the

ends -of said shaft projecting beyond the wagon-bed and a crank-arm at one end connected to one of the brake-shoe arms; a double crank at the opposite end of said shaft, one end of which is connected to the adjacent arm, and the other end connected to an operating-lever.

2. The combination of a Wagon-body, of a pair of brackets sec urediat each side thereof, the upper bracket of each pair extending through the side'of the bed and the lower one transversely of the wagon-bed supported in In testimony whereof we afx our signabrackets in front of said arms; the ends of tures in presence of two witnesses. said shaft projecting beyond the wagon-bed ROGER J. ONG.

and a crank-arm at one end connected to one ofthe brake-shoe arms; adonble crank at the ANDERSON J' DOUGLAS' opposite end of said shaft, one end of which l Vitnesses:

is connected to the adjacent arm, and the A. GUTMANN, other end connected to an operating-lever. l
